[0022] Specifically, in this embodiment, a base 1 is included, a turntable 4 is arranged on the top of the base 1, the turntable 4 is circular, a double-thread screw 7 is connected to the inside of the turntable 4 through a bearing, two ends of the double-thread screw 7 have two threads with opposite spiral directions, and the double-thread screw 7 passes through the center of the turntable 4, and a slide groove 6 is opened on the outer walls of both sides of the top of the turntable 4, and a slider 8 is slidably connected to the inside of the slide groove 6. The double-thread screw 7 is connected to the slider 8 through a thread, and when the double-thread screw 7 rotates, it can drive the two sliders 8 to approach each other, and a circular arc plate 9 is fixed on the top of the slider 8, and the midpoint between the two circular arc plates 9 is at the rotation of the turntable 4. On the center line, the side wall of the arc plate 9 is provided with a concave surface 10, and a shaft tube body 5 is provided between the two arc plates 9. The shaft tube body 5 is a fixed automobile shaft tube. The arc radius of the concave surface 10 on the arc plate 9 is the same as the bottom end radius of the shaft tube body 5. A hand wheel 11 is fixed to one end of the double-groove screw 7, and the double-groove screw 7 can be conveniently rotated by the hand wheel 11. A dial indicator 16 is provided on one side of the shaft tube body 5. The dial indicator 16 is used to detect the circular runout amplitude of the shaft tube body 5. A vertical adjustment component 21 is provided on one side of the dial indicator 16, and the vertical adjustment component 21 can drive the dial indicator 16 to move up and down.

[0023] The utility model provides an automobile axle tube detection fixture, which can simultaneously drive two arc plates 9 to approach each other synchronously through the rotation of a double-groove screw 7, so that the arc plates 9 clamp and fix the axle tube body 5, and the concave surface 10 on the arc plates 9 can automatically center the axle tube body 5, making it more convenient to position the axle tube body 5 during circular runout detection.

[0024] In another embodiment provided by the utility model, the vertical adjustment component 21 includes a vertical rail 12, and a lateral adjustment component 17 is provided on the top outer wall of the base 1. The output end of the lateral adjustment component 17 is fixed to the vertical rail 12. The lateral adjustment component 17 is a prior art.

The respective axis lines of the output shaft of the motor 3, the rotating shaft 2, the turntable 4 and the shaft tube body 5 are all on a straight line, and the motor 3 is used to drive the rotating shaft 2 and the turntable 4 to rotate, thereby causing the shaft tube body 5 to rotate.

[0026] Working principle: when the shaft tube body 5 needs to be fixed, the shaft tube body 5 is placed on the turntable 4, and then the double-groove screw 7 is rotated by the hand wheel 11, so that the double-groove screw 7 drives the two arc plates 9 to approach each other, and then the two arc plates 9 support and fix the shaft tube body 5. Since the arc radius of the concave surface 10 on the arc plate 9 is the same as the bottom end radius of the shaft tube body 5, the center of the shaft tube body 5 can automatically correspond to the center of the turntable 4; then the motor 3 drives the rotating shaft 2 to rotate, so that the rotating shaft 2 can drive the turntable 4 and the shaft tube body 5 to rotate; then the hand wheel 2 15 drives the screw rod 13 to rotate, so that the screw rod 13 can drive the connecting block 14 and the dial indicator 16 to move up and down, and the lateral adjustment component 17 can drive the dial indicator 16 to move left and right, so that the dial indicator 16 can measure the circular runout of multiple points of the shaft tube body 5, so that the circular runout measurement is more accurate.
